The Universe Quiz

Which statement best describes both models?

• A.

  Model X is the heliocentric model in which Earth is the center of the solar system; model Y is the geocentric model in which the Sun is the center of the solar system.

• Model X is the geocentric model in which the Sun is the center of the solar system; model Y is the heliocentric model in which Earth is the center of the solar system.

• Model X is the heliocentric model in which the Sun is the center of the solar system; model Y is the geocentric model in which Earth is the center of the solar system.

• Model X is the geocentric model in which Earth is the center of the solar system; model Y is the heliocentric model in which the Sun is the center of the solar system.

Which of the following scientists would have argued for a geocentric model of the solar system?

• Ptolemy

• Kepler

• Galileo

• Copernicus

Who first proposed a heliocentric model of the solar system?

• Copernicus

• Ptolemy

• Brahe

• Galileo

Hubble's research showed that the observable universe is

• stationary.

• expanding.

• cyclical.

• contracting.

How did Galileo's observations support Copernicus's ideas of a heliocentric solar system and NOT the accepted geocentric model?

• He observed how the constellations move across the night sky.

• He used a telescope to observe moons orbiting the planet Jupiter.

• He accurately measured the distance from Earth to the Sun.

• He made careful observations of solar eclipses.

How have models of Earth's position in the solar system changed over time?

• A. 

  Original models showed the Moon in the center of the solar system, and current models show Earth at the center, orbited by the Sun and Moon.

  Original models showed the Sun, not the Moon, in the center of the solar system. Current models have the Sun in the center of the solar system, orbited by the Earth and Moon system.

• Original models showed Earth in the center of the solar system, and current models show the Moon at the center, orbited by the Sun and Earth.

  Current models have the Sun in the center of the solar system, orbited by the Earth and Moon system.

• Original models showed the Sun in the center of the solar system, and current models show Earth at the center, orbited by the Sun.

  The earlier geocentric model had Earth, not the Sun, in the center of the solar system. Current heliocentric models have the Sun, not Earth, in the center of the solar system.

• Original models showed Earth in the center of the solar system, and current models show the Sun at the center, orbited by Earth.

  Earlier beliefs were based on the geocentric model where Earth was the center of the solar system. Current beliefs support the heliocentric model where the Sun is the center of the solar system.

What is the biggest difference between the geocentric and heliocentric models of our solar system?

• In the geocentric model, Earth is at the center of our solar system. In a heliocentric model, the Sun is at the center of the solar system.

• In the geocentric model, the Sun is at the center of our solar system. In a heliocentric model, Earth is at the center of the solar system.

• 
  In the geocentric model, Earth revolves around all planets in the solar system. In a heliocentric model, the Sun revolves around all planets in the solar system.

• In the geocentric model, the Sun revolves around all planets in the solar system. In a heliocentric model, Earth revolves around all planets in the solar system.

• Ptolemy and Copernicus would both use the heliocentric model

• Ptolemy would use the geocentric model and Copernicus would use the heliocentric model.

• Ptolemy would use the heliocentric model and Copernicus would use the geocentric model.

Read the passage "The Geocentric Model" in the box below.

Ancient scientists believed in the geocentric model, which stated that Earth was the center of the solar system, as evidenced by the motion of celestial bodies throughout the sky each day. However, as knowledge and technology improved, other ideas began to emerge. With the advent of the telescope, the path of the solar system's bodies could be more accurately determined. New evidence began to emerge, and eventually a new theory, the heliocentric, or Sun-centered, solar system, was developed.

Why did the knowledge about Earth's position in the solar system change?

• because scientists could not find enough evidence to support their original solar system theories

• 
  because celestial bodies changed their positions in space and eventually Earth orbited the Sun

• because new technology gave scientists new evidence that changed their interpretation of celestial movement

• because new technology made it easier for scientists to think of more plausible stories to describe natural events
